EricCressey.com: Troubleshooting the Prone 1-arm Trap Raise 

Brilliant video demostration & explanation. Quality advice and concisely delivered. Thanks for the consistent exceptional quality, informative clips

Thanks Eric once again insightful, thoughtful and clear info.

Great exercise review with a whole body look/evaluation. Some times start upright to get them moving the scapula on the rib cage then progress to prone

Excelent material Eric! Thank you very much.

Great work. What are your thoughts on placing the ipsilateral foot on the ground. I've found this helps to stabilize the entire movement, plus we can focus on creating creating intra-abdominal pressure...Just a thought!

this is great thanks eric

Is it ok to do this exercise on a bench angled instead? I don’t have a table like this

In many cases I think shirt off would make things clearer. Modesty has to take second to clarity of movement .

What's your opinion on a YTWL set for just 3 reps each with 5 lbs (and still resting between movements if necessary). I do this as part of my warmup on upper body days. I can't see how it would do any harm, but was curious to see if you thought it was a waste of time.

Awesome!

Can I do this with rotator cuff tendonitis?

I am a big fan on your channel and your work. But in all honesty, the problem is the way most baseball players throw. Throw submarine or underhand. It will save your arm and your shoulder.
